Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production and packaging detection, in particular to a cigarette box missing strip detection device based on machine vision. Background Art

[0002] The machine vision cigarette box missing strip detection device is an efficient and accurate tobacco production inspection equipment. It mainly uses machine vision technology to detect whether there are missing strips in the cigarette box. The working principle of the machine vision cigarette box missing strip detection device is mainly based on image processing technology. Specifically, the device first uses a camera to collect an image of the stacked cigarette strips inside the cigarette box, and then converts the image into a digital signal for processing. During the processing, the device will divide the pixels into black and white categories according to the set values, and identify whether there are missing strips by analyzing the area, position, shape, angle and other data of the black and white areas of the entire image. When a missing strip is detected, the device will issue an alarm signal and display the missing strip information for traceability.

[0003] Existing machine vision-based cigarette box missing strip detection devices generally perform photography and detection on the upper part of the cigarette box during transportation. However, when the swing covers on the four sides of the upper part of the cigarette box block the cigarette strips in the cigarette box during transportation, there are problems such as inaccurate detection and impact on the operation of the detection process. Therefore, we propose a cigarette box missing strip detection device based on machine vision. Utility Model Content

[0006] A device for detecting missing cigarette strips in a cigarette box based on machine vision comprises: a conveyor and a detection component; the conveyor comprises a box conveyed at its upper end, cigarette strips stacked in the box, and swing covers at the four sides of the top of the box; the detection component comprises a mounting cylinder movably mounted on the upper part of the center of the conveyor, a plurality of groups of open slots arranged and extending through the mounting cylinder, support rods movably mounted on the lower parts of the open slots, fixed blocks fixedly mounted on the outer sides of the upper parts of the support rods, wiring harnesses fixedly connected to the upper ends of the fixed blocks, a fixed disk fixedly mounted on the upper part of the wiring harness, an electric push rod fixedly mounted on the top of the mounting cylinder and connected to the fixed disk for driving, a fixed seat fixedly mounted on the bottom of the mounting cylinder, and a visual camera fixedly mounted on the bottom of the fixed seat.

[0007] Preferably, a rotating shaft is movably mounted on the upper portion of the support rod, and both ends of the rotating shaft are fixed to both sides of the opening slot.

[0008] Preferably, an inner diagonal rod is fixedly installed at the bottom of each support rod.

[0009] Preferably, a support arm is fixedly mounted on one side of the mounting tube.

[0010] Preferably, a cylinder is fixedly mounted on the bottom of the support arm.

[0011] Preferably, a support seat is fixedly installed between the bottom of the cylinder and the side plate of the conveyor.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0013] 1. In this utility model, when the visual camera at the bottom of the mounting tube inspects the tobacco rods in the box, the mounting tube can first be moved to the upper part of the box by the outer end cylinder. Then, the fixed plate lifted by the electric push rod at the top of the mounting tube pulls the four sets of support rods at the four sides of the bottom of the mounting tube to open, thereby opening the swing covers on the four sides of the box. This avoids the problem of the four swing covers blocking the tobacco rods in the box and affecting the detection accuracy and detection process.

[0014] 2. In the present invention, the inner oblique rod fixedly installed at the bottom of the support rod mainly facilitates the movement of the bottom of the support rod into the box, thereby reducing the space at the bottom of the support rod to prevent the problem of inconvenience in moving into the box and inconvenience in opening the four sides of the top of the box to shake the lid.

A support seat 214 is also fixedly installed between the bottom of the cylinder 213 and the side plate of the conveyor 100.

[0026] Specifically, the machine vision cigarette box missing strip detection device is an efficient and accurate tobacco production detection equipment, which mainly uses machine vision technology to detect whether there are missing strips in the cigarette box; the working principle of the machine vision cigarette box missing strip detection device is mainly based on image processing technology. Specifically, the device first collects the image of the stacked cigarette strips inside the cigarette box through a camera, and then converts the image into a digital signal for processing; when the visual camera 209 at the bottom of the mounting tube 201 at the upper end of the conveyor 100 detects the cigarette strips 102 in the box 101, the mounting tube 201 can first be driven by the outer end cylinder 213 to move downward to the upper part of the box 101, and then through The electric push rod 207 on the top of the installation tube 201 lifts the fixed plate 206 inside it to pull the four groups of support rods 203 on the four sides of the bottom of the installation tube 201 to open, so as to open the swing covers 103 on the four sides of the box 101, so as to avoid the problem that the detection accuracy and detection process are affected by the obstruction of the four-sided swing covers 103 during the detection of the tobacco rods 102 in the box 101. At the same time, the inner inclined rod 211 fixedly installed at the bottom of the support rod 203 can mainly facilitate the movement of the bottom of the support rod 203 into the box 101, thereby reducing the space at the bottom of the support rod 203 to prevent the problem that it is inconvenient to move into the box 101 and it is inconvenient to open the swing covers 103 on the four sides of the top of the box 101.

[0027] The working principle and use process of this utility model:

[0028] The conveyor 100 will stop running after transporting the box 101 at its upper end to the bottom of the visual camera 209. At this time, the cylinder 213 at the upper end of the support seat 214 will be started to move the installation cylinder 201 downward as a whole, so as to move the inner inclined rod 211 and the support rod 203 at the bottom of the installation cylinder 201 to the inner end of the box 101. After the inner inclined rod 211 and the support rod 203 move to the inner end of the box 101, the electric push rod 207 at the top of the installation cylinder 201 will be started to move the box 101 to the bottom of the visual camera 209. The fixed plate 206 at the inner end is driven to move upward. After the fixed plate 206 moves upward, the harness 205 connected between the bottom and the four-side support rods 203 will pull the support rods 203 and the inner oblique rods 211 at the four sides of the bottom of the installation tube 201 to open, thereby opening the rocking cover 103 at the four sides of the upper part of the box 101, so as to ensure that the visual camera 209 at the bottom of the installation tube 201 can shoot the tobacco rods 102 in the box 101 without obstruction, thereby ensuring the detection accuracy of the visual camera 209.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
